I have a matrix A
:
1 3 1
7 5 2
4 3 7
8 2 1
3 9 6
4 5 2
and a matrix B
:
2 9 1
4 3 8
9 7 3
4 4 2
6 5 7
2 9 2
I want to compute C
:
1*2+3*9+1*1
7*4+5*3+2*8
4*9+3*7+7*3
8*4+2*4+1*2
3*6+9*5+6*7
4*2+5*9+2*2
How can I express this purely using matrix operations? I realize I can do this using .
versions but I am interested in pure matrix operations. For example, when I have two vectors x
and y
, I vastly prefer x'*y
over sum(x.*y)
. Hence I am interested in how to do the above also using matrix operations.
